    Thanks for your suggestion. However, I suppose range is measured from the station right? Not the distance between two aircrafts can be taken as the reception range of the antenna...

    Is that all feeders in Kaohsiung using this amazing DIY antenna?

    It seems the reception range of feeders in Kaohsiung is quite good and even better than us in Hong Kong as we don't know how to DIY...

    壓克力板 - Acrylic Sheet
    銅片 - Copper Foil
    內芯 - Internal Cylinder (Tube)
    接地端小段 - Small Part of GROUND
    去皮 - Without Skin
    鋁箔部分 - Aluminium Foil Part
    熱縮管 - Heat Shrink Tube
    焊槍 - Welding Gun
    線+頭 長度不限 - Wire+Plug, Unlimited Length

    Pic2:
    Fix the copper foil on Acrylic Sheet, hot melt glue is pasted behind the copper foil.
    Using Insulating Tape to avoid displacement of copper foil after melting.

    Pic3:
    Weld 5C2V Internal Cylinder (Tube) on the copper foil
    Try your best to weld it beyond boundary, to avoid data error

    Pic4:
    Weld the 3 beard

    Pic5:
    Connect Plug
    Connect Copper Foil nearest
    Each Internal Cylinder (Tube) connecting in series to get the best reception

    Pic8:
    Welding Point is covered with hot melt glue

    Pic9:
    Finally Heat Shrinkable Tube, FINISHED!!!
